CARBURETER.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed. April 7, 1913. Serial No. 7 59,277.

To all whom it may concern:

Be it known that I, Lnsrnn G. POND, a citizen of the United States, residing at Seekonk, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Carburetors, of which the following is a specification.

This invention relates to certain new and useful improvements in carburetors, and the primary object thereof is to provide a device of this type which has novel and improved means for accurately controlling the rich- .ness of the combustible mixture.

A further object of the invention is to provide a carburetor which has a gasolene satu rated wick, or the like, and means for controlling the entry of air, after contact with the wick, into the mixing chamber, which means has a diagonal relationship to the wick, so that the richness of the mixture may be controlled in varying degrees.

In the drawings-Figure 1 is a perspec tive view of the invention applied in position on an automobile, the latter being shown in fragmentary section. Fig. 2 is a central horizontal section of the invention. Fig. 3 is a fragmentary top plan view of the front of the apparatus. Fig. 4 is a section on the line 4-4 of Fig. 2. Fig. 5 is a detail perspective view of the controlling valve for the air, and Fig. 6 is a similar view of the air controlling slide. Fig. 7, is a fragmentary detail perspective view of a part of the means for rocking the air admission valve.

The invention embodies a mixing chamber 1 that has an outlet 2 which connects with the cylinders 3 by means of the manifold pipe connections 4. Attached to one end of the chamber 1 is a casing 5 that has a closed end 6, the upper portion of the casing being cut away at 7. Rotatably mounted in the casing 5 is a tubular or hollow cylindrical air controlling valve 8 which latter has a closed end 9 that abuts the closed end 6 of the casing 5, the end 9 having a threaded stem 10 which extends through the end 6 of easing 5 and has a cranked outer end 11 which is connected by means of a link 12 to an oscillatory member 13. The member 13 and link 12 have a pin and slot connection 14, and a rod 15 has the member 13 rigidly connected thereto, whereby rotary movement imparted to the rod, by means, for instance of a handle 16, will effect corresponding rotation of the valve 8. The means described for rotating the valve 8 is shown merely by way of example, since other approved or desired means may be readily substituted. Mounted on the interior of the valve 8 is a tubular open ended slide 17, which is of less length than the valve 8 and at its inner end has a spider 18 to which a rod 19 is rigidly connected. A dished ballle plate 20 is rigidly mounted on the rod 19 and is located in spaced relation to the inner end of the slide 17, the outer end of the rod 19 extending through the rear end of the chamber 1 and being connected to a pivoted lever 21 which latter is connected to a rod 22. The rod 22 is operated by a foot pedal 23 to move the slide 17 along the length of the valve 8. Means other than that just described may be used to operate or manipulate the slide 17, since the means herein disclosed, like the means for rotating the valve 8, is merely shown by way of example.

Carried by the casing 5 is a wick chamber 24 which in turn is connected to a gasolene chamber 25 in which is a float 26, a port 27 between the chambers 24 and 25 enabling gasolene to enter the former from the latter. The float controls the quality of gasolene admitted to the chamber 25 through a valve 28 by any suitable means, for example a bell crank lever 29 connected to the valve and a horizontal lever 30 that is pivoted to the chamber 25 and to the lever 29, the valve 28 being located in a pipe 30 which leads from the source of supply.

A wick 31 has its lower end submerged in the gasolene in the wick chamber 24 and has its upper end disposed at right angles to its lower end, so as to present a vertical edge 32 into a slot 33 that is formed in the valve 8. The wick becomes saturated with the gasolene, and the air that contacts there with is drawn by suction through the slot 33 of the valve 8 and thence into the interior of the hollow slide 17, at the end 17 thereof (Fig. 3) whence the air passes through the interior of the hollow slide 17, past the web 18 thereof and against the battle 20, which latter throws the mixture rearwardly of its direction of travel and against the walls of the chamber 1 that surrounds the baflle, thereby causing thorough mixing of and intimacy between the air and gasolene, prior to exhaust of the resultant mixture through the outlet 2.

In order to govern the richness of the mixture, the valve 8 may be turned so as to cover or uncover more or less of the slot 33, thereby controlling the amount of air that is permitted to enter the chamber l l By moving the slide 17 toward the'r'ear end of the body 1 the end 17' oft-he slide will uncover the slot 33 at the front end of the latter to allow a greater quantity of air to which latter at the front end of the valve 8 terminates in a comparatively short wall 33", the latter being disposed parallel to the other side wall of the slot, said last named side wall of the slot being parallel to the longitudinal axis of the valve. By referring to Fig. 3 of the drawings, it will therefore be seen that the wall 33 has a diagonal relationship to the vertical edge 32 of the wick, and by rotating the valve 8 it will be seen that a wedge shaped space for the air that enters the slide 17 will be provided. This wedge shaped space is an advantage in that the strata of air which is at the widest part of the slot or wedgeshaped space will not come in contact wit 1 the gasolene that is held by the wick, which further allows the richness of the mixture to be varied. When the slide 17 is moved so that its end 17 is at the inner edge of the wall 33 of the slot, it will be seen that the entrance to the slide is a substantially rectangular one, and that when the slide 17 is. moved toward the chamber 1 the entrance into the slide will be of wedge-shape, thus allowing further variations in the richness of the mixture to be obtained.

From the above it will be noted that the air is drawn over the wick, and then enters the space between the wick, the end 17 of the slide 17, and the slot 33, from whence the mixture passes through the slide and contacts with the battle and then egresses through the outlet 2 and manifold 4: to the cylinders 3. 7
